Pros: Easy to use, sharpens quickly and can also sharpen serrated knives
Cons: Can't sharpen ceramic blades or curved blades or blades with a grind on one side
I had a Chef's Choice 130 electric sharpener for several years and bought the Smith's Adjustable Edge Pro Electric Knife Sharpener (SAEP) several months ago because it allowed you to manually adjust the sharpening angle for the style of the knife you wanted to sharpen (chef's, santoku, paring, utility, boning, fillet, pocket knife, hunting/outdoor knife, etc).
The owners/user manual lists the sharpening angles for Global, Henckle/Cronidur, Shun, Wusthof, and Zwilling. For those knife manufacturers that are not listed in the manual, you can go on line and get the sharpening angle for that particular knife, which I did for my Kramer's chef's knife and my Victorinox's chef's knife.
It took a few minutes to get use to feeding the knife blade into the sharpening slots because when you sharpen a blade you sharpen both sides at the same time and you don't have a flat edge to rest the knife blade on like you do on the Chef's Choice Sharpener. On the SAEP, there are two sets of sharpening wheels in each slot that sharpens each side of the blade at the same time. The sharpening wheels slightly pull the blade into the wheels to be sharpened and you manually pull the blade across the sharpening wheels.
The SAEP has a coarse slot that uses diamond coated wheels and a fine slot that uses ceramic wheels. It also has a push out sharpener to manually sharpen serrated knifes. When I used it to sharpen my serrated knife, it seemed to be a disjointed effort to do it but it sharpened the serrated knife cut paper once sharpened.
I spent about an hour reading the manual and sharpening my knives (9 assorted Wusthofs, 1 Kramer, 1 Victorinoix, 1 Shun, 1 Global and 1 Cutco Butcher's Knife that I bought from a college student who was the son of a friend of my wife's that we had invited over for a dinner that I cooked for all....long story.
After sharpening each knife back to the manufacturer's specks, each knife easily passed "the cutting paper test".
It took me about 20 pulls for each knife in each slot to get it to the sharpness the first time using the SAEP.
